Here is the problem:
If a parabola is the graph of the equation
y = a (x-6)[sup:67ow5x6f]2[/sup:67ow5x6f] -17
a. What are the coordinates of the vertex? (6,-17)
Will the vertex change if a changes? No. Yes.
b. What is the value of stretch factor a if the y-intercept is (0,1)?
c. What is the value of stretch factor a if the graph goes through the point (3, -44)?
I figured out a, but I don't have the slightest idea how to do either b or c. If someone could possibly help me, I would greatly appreciate it. Takk!
